A couple of patches in this small series. The first patch addresses a problem with large write same (or zeroout) block layer calls being split into commands that are not aligned on the device physical block size. This will work on regular disks but is not optimal. The commands will however fail with host-managed zoned block device if the commands target sequential write required zones. The patch simply makes sure that the maximum write same sectors is aligned to physical block sizes. This solution can be implemented here in sd_config_write_same() or in the block layer (__blkdev_issue_write_same() and __blkdev_issue_write_zeroes()). Please let me know if you prefer a block layer solution. The second patch does not introduce functional changes. As always, comments are welcome ! changes from V1: * Removed useless addition of blank line an indentaion change in first patch.
